Abstract

PCT No. PCT/EP90/02242 Sec. 371 Date Oct. 21, 1991 Sec. 102(e) Date Oct. 21, 1991 PCT Filed Dec. 19, 1990 PCT Pub. No. WO91/09389 PCT Pub. Date Jun. 27, 1991.An infrared detector particularly well suited for the detection of heat sources, specifically from fires in an outdoor environment. The infrared detector comprises an infrared sensor receiving infrared radiation from a focused refractive optical unit. The infrared radiation from the optical unit is appropriately filtered so as to optimize the reception of infrared radiation by the detector in a frequency band of within about 2.5 to 5 microns. The sensor is configured utilizing a linear matrix of individual infrared sensing elements which may be flexibly applied to modify the field of view of the sensor. The detector contains appropriate power and signal amplification circuitry so as to provide an electrical output signal corresponding to infrared radiation received in the desired frequency band. The entire detector may be housed in a hermetically sealed unit appropriate for outdoor use and mounted on a movable pedestal for inclusion in an overall fire protection system such as, for example, a forest fire detection and warning system.
